IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 35,077, dated Apri] 29,1862.

To cLZZ whom 'ZZ may concern:

Be it known that l, JAMES BUDD, of Sandy Ilill, in the county otVashington and State oi' New York, have invented a new and usei'ulImprovement in Pumps, designed more especiall y for Fire-Engines; and Ido hereby declare that the following is a full, clear, and exactdescription ofthe same, reference being had to the accompanyingdrawings, making a part of this specification, in which- Figure l is avlongitudinal vertical section of my invention, taken in the line 5c,Fig. 2. Fig. 2 is a transverse vertical section of the same, taken inthe line y y, Fig. l.

Similar letters of reference indicate Corresponding parts in the twofigures.

The object of this invention is to obtain a pump by which water can bedrawn simultaneously from two different fountains or reservoirs, ordrawn from either separately, as desired, and also ejectedsimultaneously from two different nozzles or eduction-pipes, or fromeither separately, and at the same time not involve the necessity' ofany complicated arrangement of parts, but one which will admit of thepiston being operated by a short stroke and a rapid movement.

To enable those skilled in the ait to fully understand and construct myinvention, I will proceed to describe it.

A represents the pump-cylinder, which is in a horizontal position, and Bthe piston, the rod C of which passes, as usual, through a stuffing-box,D, at one end of the cylinder. The piston B is formed of two parts, Laf, of cup form, in each of which a ball-valve, E, is placed, and whichwhen closed cover openings h Z) in the inner sides of the cups. The cupsor parts a a of the piston are connected atI a suitable distance apartby curved arms c, which project from a central tube, as shown in Fig. l.F is the induction-pipe,\vliich communicates with the cylinder A at thecenter of its lower side, and G is a retainingvalve, which is placed ina chamber, G, with which the induction -pipe F communicates, as shown inFig. 2.

On the upper part of the cylinder A there is placed a valve-chamber, Il,which is divided into two compartments, c e', byavertical centraipartition, f, each compartment beingprovided with a ball-valve, g, bothof which are shown in Fig. l. The compartments c ecommunieate at theirlower part-s, respectively, with water-passages 71l h', which aredivided by a partition, t', and communicate with the ends of thecylinder A.

On the valve-chamber l-l there is placed an air-chamber, I, having avalve, J, at its lower part opening upward. To the upper end of theair-chamber I an eduction-pipe, K, is attached. The upper end of thepipe K communicates with a chamber, L, which has two nozzles, M M',connected with it, one at its upper end and the other at its lower end,and within the chamber L there is placed a valve, N, which has twoseats, jj', one being above and the other below the orifice of the pipeK. (See Fig. l.) The stem O of the valve N passes through astuffing-box, P, at the upper end of the chamber L, so that the valveNmaybe adjusted to fit in either seatj or j', or be so adjusted as not tobe in Contact with either, in which position it is shown in Fig. l indark Shading.

Q is a pipe, which also serves as an induction-pipe and communicateswith the chamber G', in which a valve, S, is placed, the seat It ofwhich is above the valve G and lower end of the induction-pipe F. Theinductionpipe F is continued by connecting an additional length to thelowerend of the chamber G. The valve S is provided with a stem, T, whichpasses up through a stufingboX,U, on the upper end of the chamber G, andhas a nut, V, on its upper part, said nut being provided with twopendent arms, Z Z, which fit in a spiral groove or slot, m, in acup-shaped ange or projection, W, on the top of chamber G. (See Fig. LThe nut, with its arms and the spirally-grooved cup-shaped flange orprojection, serves as ameans for raising and lowering the valve S. Otherdevices, however, may be employed for the purpose.

The operation is as follows: The piston B may be operated by hand orother power, the length of the stroke of the piston being equal to thelength of the space between the two parts a a of the same, so that theinductionpipe F will always communicate with the cylinder A between thetwo parts of the piston, as will be fully understood by referring toFig. 1. lVhen the piston B is moving in the' direction indicated by thearrow l, the water in cylinder A in front of the piston is forced upthrough the passage h into the compartment c 'of the valve-chamber H,the valve g rising under the pressure of the water, au d the latterpassing up through or around valve J into the air-chamber I, and upthrough the eduction-pipe K into chamber L, fromwhich, if the' valveN beadj usted midway between its two seats jj', the water will escapethrough both nozzles M M', and if the valve S in the chamber G' beadjusted down from its seat 7a the water will be drawn through bothpipes F' Q, into the pump-cylinder, as indicatedby the arrow 2. W'henthe piston B moves in the opposite direction, as indicated by the arrow3, the water in the back part of the cylinder A, behind the piston B,which was drawn into it by the previous movement of the piston, isforced up through the passage h' into the chamber e', and thence upthrough valve lJ into the air-chamber I and through the eduction-pipe Kand out of the nozzles M M', the front part of the cylinder A being lledwith water during this backward movement of the piston. If it should bedesired to draw water through the pipe F' only, the valve S is drawn upagainst its seat 7c, as shown in red outline, Fig. 2, so as to out offpipe Q from the chamber G', and in case it should be required to drawwater through the pipe Q only valve S is lowered in chamber G', so thatthe lower end of its stem T will bear upon the upper end of the stem ofvalve G and keep the latter closed, and the water may be forced out ofeither of the nozzles M or M' by adjusting the valve N against the seatj or j', which forms the communication between the nozzle to be cut offand the chamber L. The valve N may be adjusted in the same way as valveS, or by other suitable means. By the construction of the piston B andits arrangement relatively with the induction-pipe F, as shown, thepiston B may be operated with a short stroke and a very rapid movementanimportant result in a pump designed for a fireengine--and by having thetwo inductionpipes F' Q connected with the chamber G', provided with thevalves .G and S, arranged substantially as shown, to admit of the waterbeing drawn through either or both pipes simultaneously, a greatadvantage is obtained, for the pump may be supplied from two fountainsor reservoirs at diierent heights, the higher one being used untilexhausted, and then the supply taken from the lower one, the changebeing made without the loss of time in shifting and adjusting hose, thevalve S only requiring to be adj usted, which may be done in a moment oftime. An equal advantage is also obtained bythe arrangement of the twonozzles M M and the valve N, by adjusting which two streams may bethrown from the pump', or one only from either nozzle.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

l. The two induction-pipes F' Q, in combination with the chamber G',provided with the valves G S, and all arranged substantially as and forthe purpose set forth.

2. The combination and arrangement of the two nozzles M M', chamberv L,and valve N, and eduction-pipe K, substantially as and for the purposeset forth.
